With reference now to the drawing, particularly FIGS. 1-5 thereof, there is shown and illustrated a novel and improved separable fastener constructed in accordance with the principles of the present invention and designated generally by the reference character comprising a male member or portion 22, a female or housing member or portion 24 and a cross bar member or portion 26.

The male member 22 may be comprised of an elongated rectangular frame member 28 forming a fenestration 30. At the forward end of the frame member 28, integral therewith and projecting into fenestration 30, there may be provided a resilient tongue member 32, said tongue member 32 being narrower than the frame member 28 so that when disposed upon the same plane as the frame member 28, the tongue member 32 is adapted to fit within the fenestration 30. Said tongue member 32 is disposed upon an oblique plane and is provided with a shoulder 34 and a lip 36 at the free end portion thereof. Projecting from the rear of said frame member 28, there may be provided a neck portion 38 connecting the frame member 28 with a connecting portion 40. The connecting portion 40 may be of substantially rectangular eyelet configuration provided with a generally rectangular slot 42 extending there through generally perpendicular the plane of the frame member 28 with the longitudinal axis thereof generally parallel the shoulder 34. Accordingly, a strap member 44 defined by a free end portion 46 and a standing portion 48 may be passed through the slot 42, as shown, and the free end portion 46 thereof secured with the standing part 48 thereof, as by securing means 50 such as a rivet, as shown, or adhesive, line of stitching, or the like, so that the male member 22 is substantially fixedly positioned on the strap 44 although it is to be expressly pointed out that the attaching portion 40 may be of substantially any desired construction or arrangement as may be known in the fastener art such as, for example only, and without limitation, as is shown in my prior U.S. Pat. No. 3,200,464. The connecting portion 40 is preferably of greater width and depth than the plate portion 28 so as to define adjacent thereto a generally rectangular shoulder 52 extending therearound.

The housing or female member 24 is of sufficient width and depth to accommodate the frame member 28, and is preferably comprised of a pair of oppositely disposed generally parallel spaced apart side walls 54 and 56, a rear or end wall 58 perpendicularly disposed thereto at a rear end portion thereof, and a pair of generally parallel spaced apart generally plate-like portions extending thereacross defined by, for example, pairs of generally parallel spaced apart inwardly disposed shoulders 60 and 62, 64 and 66, and 68 and 70, respectively, together with a forward pair of transverse bars 72 and 74 generally parallel to the transverse axis of the female housing member 24 extending generally between the shoulders 60 and 64 and 62 and 66, respectively, at one end portion thereof and with a pair of intermediate transverse bars 76 and 78 in generally spaced apart parallel relationship generally intermediate the housing member 24. Accordingly, four fenestrations, 80, 82, 84 and 86 may be defined in the plate-like portions by the shoulders and transverse bars with the fenestrations 80 and 82 being in general axial align ment with one another and the fenestrations 84 and 86 being similarly in general axial alignment with each other, the fenestrations 80 and 82 being disposed at one end portion of the housing member 24 and the fen estrations 84 and 86 being disposed at the other end portion thereof. Further, a transverse or forward opening or aperture 88 is formed at one end portion of the housing member 24 of generally rectangular configuration defined by the forward transverse bars 72 and 74 and the forward end portion of the side walls 54 and 56. Further, the side walls 54 and 56, together with the end wall 58 and with the shoulders 60, 62, 64 and 66 define, extending generally inwardly of the housing 24 from the transverse aperture 88 extending past the fenestra tions 80, 82, 84 and 86.

The cross bar 26 is adapted to be inserted into the housing 24 through the transverse aperture 88 until disposed extending across the fenestrations 84 and 86 and, when so positioned, the free end portion 90 of a strap 92 may be passed through the fenestration 84, be tween the cross bar 26 and the intermediate transverse bars 76 and 78 of the housing 24, through the fenestration 86, back through the fenestration 86 and past the cross bar 26 generally between the cross bar 26 and the end wall 58 so that, upon tension being applied to the strap member 92 the cross bar 26 would be urged towards the end wall 58 to clamp the strap 92 generally between the shoulders 68 and '70 and the cross bar 26. On the other hand, when no such tension is applied, it may be seen that the strap member 92 may be readily passed by the cross bar 26 so as to provide an adjustable attachment therebetween.

ln inserting the male member 22 through aperture 88 of the female housing member 24, the frame member 28 is restrained from any lateral movement by the walls 54 and 56 and restrained in its forward movement by the engagement of the generally rectangular angular wall 52 against the forward end of the housing member 24. The frame member 28 is restrained against any rotation relative the female or housing member 24 by means of the shoulders 60, 62, 64 and 66 engaging the male member 28. As the frame member 28 is introduced into the cooperating female or housing member 24, the tongue 32 is depressed by the forward transverse bar 82 until the shoulder 34 abuts the inner sur face of the transverse bar 82 and partially projects upwardly into the fenestration 68. Then, the frame member 28 will be securely contained and held against relative movement within the female or housing member 24. It will be noted that any reverse pull upon male member 22 will not effect removal of the frame member 28 until pressure is applied to the tongue 32 to depress it sufficiently to allow the shoulder 34 to clear the forward transverse bar 62 and hence allow removal of the frame member 26 from the female or housing member 24.

The tongue member 32 is biased, through the resilience or memory of the plastic forming the male member 22 generally outwardly of the fenestration 30 and into the respective fenestration of the female or housing member 24 and is retained therein by means of engagement of the lip 36 against the inner surface of the transverse bar 82.

In order to provide an aid to the user in depressing the tongue member 32, the surface thereof may be provided with slip reducing means, such as a plurality of generally transverse ridges 94. Further, in order to enable the tongue member 32 to more readily pivot about its base line connection with the frame member 28, there may be provided relief means, such as a generally transversely extending curvilinear groove 96 extending substantially entirely transversely across the tongue member 32 at the intersection thereof with the frame member 28. Such groove 96 enables the tongue member 32 to readily bend thereabout while yet not adversely affecting the strength of the tongue member 32 so that the tongue member 32 may yet be of sufficient thickness as to prevent buckling during the application of tension to the fastener 20.

The cross bar member 26 may be provided with means, such as a plurality of teeth or ridges 98 extending therealong to provide increased resistance toward inadvertent movement of the web 92 relative thereto when the web or strap 92 is pulled thereagainst.

As a further aid in providing a secure adjustment of the web or strap 92 relative the female housing member 54, the edges of the cross bar 26 may, as shown, be generally cuvilinear so as to provide an increased wedging action against the housing or frame member 54. Fur ther, the cross bar member 26 may be constructed and arranged so as to be restrained against movement within the female or housing members 54in other than a direction generally parallel the longitudinal axis thereof.

For example, the shoulders 60 and 64 may be provided with generally longitudinally extending grooves 102 and 104, respectively, and the cross bar 26 may be provided with cooperating tenons or ribs 106 and 108, respectively, engageable within the grooves 102 and 104 so as to restrain the bar member 26 against twisting or rotation within the female or housing member 54. As shown, such grooves may be provided only in the walls 60 and 64, or, if desired, similar grooves may be provided in the shoulders 62 and 64. Similarly, the cross bar 26 may have such tenons or ribs extending in only one direction therefrom or the cross bar 26 may be symmetric and of generally I-shaped cross-sectional configuration having such ribs extending in both directions. Similarly, although the female or housing member 54 has been shown, illustrated and described as having two opposed fenestrations 80 and 82, enabling the male member 22 to be inserted therein in either of two positions, one side of the female or housing member 54 may be made solid and the respective fenestration eliminated.

Where, however, and as shown, the fenestrations 80, 82, 84 and 86 are each provided, the housing or female member 24 and the male member 22 may be coupled either in the position shown or rotated 180 relative one another so that the orientation therebetween at the time of coupling is not critical so as to preclude insertion of the tongue member 22 into the housing or female member 24 in a non-latching relationship.

Referring now to FIGS. 6-11, inclusive, there is shown and illustrated another embodiment or modification of separable fasteners constructed in accordance with the principles of the present invention.

With reference to FIGS. 6-11, like reference characters will be utilized for the respective parts thereof, with the exception that the reference characters are primed, it being expressly understood that the embodimentor modification shown therein is substantially the same as the embodiment or modification of FIGS. l-5 and the parts thereof are the same except where specif ically set forth as being different.

The male member 22' is provided with a tongue portion 32' which on its inclined surface is provided with a generally oblong rounded and dimpled depression 94' as an aid in preventing slippage of an operator in depressing the tongue portion 32'. The relieved portion 96' on the rear of the tongue member 32' is of generally curvilinear configuration but is further provided with a plurality of reinforcing ribs 97 to provide the desired degree of rigidity and strength thereto.

The female or housing member 24 is provided with a pair of relief grooves and 112 extending generally longitudinally thereof extending towards the inner surface of the shoulders 60, 62, 64 and 66 so as to provide narrow shoulders 114, 116, 118 and 120 for engaging the tongue portion 28 or 28' generally only along the edges thereof to thereby reduce the friction between the male member 22 and the female or housing member 24 and, further, to reduce binding or improper operation due to warpage, dimensional changes, or the presence of dead or any foreign matter therebetween.

Further, the housing member 24 has the shoulders 60 and 64 extended so as to form a back panel 63 completely subjacent the fenestration 82 so as to provide a smooth and uninterrupted surface permitting the male member 22 to be inserted therein in only one orientation. Further, the end wall 58' is provided with an elongated slot 59 through which the strap 92 may extend so as to extend outwardly of the housing or female portion 24 generally intermediate thereof and to provide a generally straight line pull thereagainst, as shown more fully particularly in FIGS. 10 and 11. In addition to providing a generally straight line pull on the strap member 92, this construction has the additional difference relative the construction of the housing member 24 in that the adjustment of the strap member 92 on the female housing member 24 may be readily and easily accomplished although the adjustment, once made, is not as secure in the absence of tension on the strap 92 while in the housing structure 24', the adjustment is less easily made but the adjustment, once made, is more positive even in the absence of tension on the strap 92. The housing structure 24, therefore, has particular utility where tension is not normally applied to the strap 92 as,

for example, in connecting the ends of a runaway strap as used inskiing to retain the ski to prevent the loss of a ski upon release of safety bindings.

As heretofore pointed out, the separable fasteners of the present invention may be molded of a plastic material and it has been found that a very high carrying capacity may be provided by the use of a fiberglas reinforced nylon.

For example, separable fasteners have been made in accordance with the present invention molded from fiberglas reinforced nylon with the male member having a width of approximately 1 5/16 inches, and a thickness of approximately one-eighth inch to the frame member with the tongue member 32 having a width of .approximately three-fourth inches, and the shoulder 34 being approximately three-thirty-second inches high for insertion in a housing member wherein the forward bar 38 is also of approximately one-eighth inch width which, after annealing at have held in excess of 400 pounds tension. Clasps or separable fasteners of these dimensions have been found, as set forth above,

particularly useful for use in connection with sporting and other outdoor equipment in that their dimensions are such that they can be readily and easily engaged and disengaged even under adverse conditions and under adverse weather, even when wearing gloves and mittens.

While the invention has been described, disclosed, illustrated and shown in terms of an embodiment or modification which it has assumed in practice, the scope of the invention should not be deemed to be limited by the precise embodiment or modifications herein described, disclosed, illustrated or shown, such other embodiments or modifications being intended to be reserved especially as they fall within the scope and breadth of the claims here appended.
